    Answer: Nebula

    Explanation:

    Nebula is a stellar nursery. Stars take birth in the molecular cloud of dust and gases - Nebula.

    This molecular condenses and forms a core which spins and gathers even more mass and becomes bigger. This process increases temperature and pressure at the center which ultimately starts nuclear fusion reaction giving birth to a star which liberates energy in the form of heat and light.

    Black-hole is the end stage of a massive star.

    Supernova is a stage which precedes formation of a neutron star or a black-hole for a massive star.

    White dwarf is the end stage of an average mass star like sun.
